# N(6.84, 1.55)1. Add appropriate scaling on the horizontal axis.2. What proportion (percent) of the scores fall below 5.29? Shade the area below.

Question

I need help with this problem i was also given a table with numbers I sent it in earlier

Step 1

A normal distribution is given with mean µ = 6.84 and standard deviation σ = 1.55.

Empirical Rule:

If a population has bell shaped distribution with mean µ and standard deviation σ ;

• Approximately 68% of the observations lie between µ - σ and µ + σ.
• Approximately 95% of the observations lie between µ - 2σ and µ + 2σ.
• Approximately all of the observations lie between µ - 3σ and µ + 3σ.
Step 2

1.

Normal distribution is a bell shaped distribution. Here using the empirical rule, the three limits for the distribution are,

Step 3

Putting the scaling in ...
